Courses in the PSS Technical division belong to the branch of diving which is generally described as "technical". This term is used to define diving activities carried out, for enjoyment, beyond the limits defined for "recreational" diving.
According to PSS, any type of dive (within no-deco stop time limits or not), if made beyond the limits established for recreational diving activities, must be considered "technical".
Obviously technical diving also has its limits that must be observed, especially during training activities.
The PSS technical diving courses are considered among the best in the world and PSS Technical Instructors are only qualified after careful selection based on their experience and the quality of their teaching.
